Pharmacological Studies on Powdered Whole Part of Unossified Antler

Systematic pharmacological studies on powdered whole part of unossified antler obtained from Cervus nippon Temminck var. mantchuricus have been carried out in mice and rats. Powdered antler, with a single oral administration, showed a very weak acute and subacute toxicity; its MLD being >5g/kg orally in mice. On daily oral treatments of the antler for 14 days, it did not cause any significant differences in body weight gain, various organ weights and serum transaminase activities compared to those of the control rats. Powdered antler, with a single oral administration, showed a remarkable analgesic activity as evaluated by writhing syndrome and tail-pressure test, a weak CNS depressant activity as well as a weak immunopotentiating action as evaluated by carbon clearance test in mice. Powdered antler, with repeated treatments, showed a moderate antifatigue effect against immobilized stress and showed significant increases in both adrenal weight and its ascorbic acid content in rats, suggesting that the mode of antifatigue effect of antler is related to adrenal and its components.
